Patent GB-589876-A (GB)
Title: Improvements in and relating to the production of mashed potato powder
IPC: A23L19/15
Filed: 1944-12-01
Abstract: Reconstitutable, cooked, mashed potato powder is prepared by cooking and mashing potatoes, freezing, thawing and removing moisture by mechanical means and converting to powder.  A centrifugal machine is preferably used to separate the moisture although a press or pressure rollers may be used so long as the starch granule-containing cells are not damaged.  Where the moisture after centrifuging exceeds 45 per cent., seed powder as defined in Specification 566,167 is mixed in to reduce it to about 40 per cent. before drying to 7-10 per cent., as is material of less than 45 per cent. moisture after centrifuging, by any of the methods referred to in Specification 566,167 or preferably by means of a pneumatic dryer such as described in Specification 566,170, [Group XIII].  The material is reduced preferably by sieving through a 12-18 mesh as described in Specification 566,167 either after the final drying or after centrifuging if the moisture content is then below 45 per cent., or after admixture with the seed powder.  The separated liquor from the thawed mass may be concentrated, e.g., in a climbing film evaporator, a vacuum pan or by spray drying and returned to the mash or seed powder before final drying or the liquor may be completely dried and the powder mixed with the dried mash.  In an example, about 2lbs. mashed potato are frozen for 2 1/2 hours in a chamber at 0 DEG F. and then removed to an air temperature of 65 DEG F. where after a further 2 1/2 hours they are fully thawed.  After squeezing in a screw press the partly dry mash is sieved through a 16 mesh sieve when it has 41 per cent. moisture and is dried by hot air.  In another example 500 grms. of mashed potato are frozen and thawed as before and then centrifuged producing a mash with about 54 per cent. moisture 200 grms. of which are mixed with 80 grms. of a seed powder containing about 10 per cent. moisture and the mixture sieved and dried. Specification 542,125 also is referred to.
Patent GB-504883-A (GB)
Title: Method of making filaments of pure silica, particularly quartz
IPC: C03B37/00
Filed: 1938-08-16
Abstract: 504,883. Making filaments of silica. SKAUPY, F., and WEISSENBERG. G. Aug. 16, 1938, Nos. 24126 and 24127. Convention dates, Aug. 19, 1937 and Aug. 1, 1938. [Class 56] [Also in Group III] A method of making filaments of silica consists in forming them from a silica compound which can be spun at a lower temperature than silica, and then freeing them from compounds other than silica by treatment with acid, and an acid salt, or other suitable reagents. An alkali-metal silicate, such as waterglass, may be used as the initial material, and this may be fused and drawn into filaments by the methods used in making glass wool. Alternatively, the waterglass may be dissolved in water or dilute alcohol and the solution treated with carbonic acid or other weak acid to precipitate part of the silica in the colloidal condition. If desired, the solution may then be centrifuged to separate a portion richer in silica, and this portion is spun into filaments. The material may be spun directly into an acid coagulating bath where it is converted immediately into filaments of silica. The fused material may be treated similarly. The filaments may be collected, however, and subsequently treated with dilute acids, or with gaseous hydrochloric acid or chlorine, to remove the basic constituents. Finally the filaments may be vitrified by passing them rapidly through a gas flame or an electrically heated zone. Colouring matter may be added to'the material before spinning.

Title: Improvements in or relating to apparatus for sorting objects according to their thickness
IPC: B07C5/08
Filed: 1956-08-07
Abstract: 827,301. Sorting by gauging thickness. BARTA, J. Aug. 7, 1956 [Aug. 8, 1955], No. 24161/56. Class 106 (2). [Also in Group II] Apparatus for sorting objects A according to their thickness comprises a measuring device 3, a holder 24, two discharge passages 10, 11, and an electric circuit comprising a first electromagnet 17 adapted, when actuated, to change the position of a directing member 14, and a second electromagnet 25 adapted, when energized, to open the holding means 24, so that objects are guided either to one of the passages 10, 11 or are retained in the holder 24 depending on their thickness. Plates A to be sorted into three groups according to their thickness are each held in a clamp 4 arranged on the periphery of a conveying wheel 5 and are brought at regular intervals between the stop 6 and the detector 7 of the measuring device 3. In the arrangement shown, if the thickness of the plate A is less than the lower limit of the second group, then a bell crank lever 29 contacts a spring 31. This closes a circuit which, by means of a relay, closes a circuit through the electromagnet 17, which thus pulls the directing member 14 to the left (as viewed in Fig. 1), clamp 4 being opened at the same time by the electromagnet 25 acting on a lever 26. An arm 37 is then moved to the right as shown in Fig. 1, withdrawing the detector 7 and allowing the plate to fall down the passage 11. If the plate A lies within the limits of thickness of the second group, lever 29 touches neither spring 31 nor spring 32, thus lever 14 remains in the position shown in Fig. 1 and the other sequence of operations being the same, the plate A falls down the passage 10. If the plate has a greater thickness than the upper limit for the second group, lever 29 is pulled by spring 36 against spring 32, thus operating a relay which breaks the circuit for the electromagnet 25. In this case, the plate remains held in the clamp 4 and is carried on by wheel 5 to further gauging devices of the same kind. If the electrical connections to springs 31, 32 are interchanged, sorting may proceed from the thickest to the thinnest plates instead of from the thinnest to the thickest. To ensure operation as above, a switch is introduced into the circuits for the electromagnets, and is closed only when the wheel 5 has brought the plate A between the gauging device. The director 14 is returned to the right as shown in Fig. 1, if necessary after every operation, by means of a slide 19 moving in accordance with the wheel 5, and the arm 37 withdraws the detector 7 from the fixed stop 6 when each operation has been completed. As described, electromagnetic relays are used to make and break the circuits for the electromagnets 17, 25. These relays may be replaced by electronic relays, and an inductive or capacitive measuring device may be used instead of the electric contact device described.
